ESP32-H2FH4S
Espressif SystemsESP32-H2FH4S is the 4 MB in-package flash variant of the Espressif ESP32-H2, a low-power single-core 32-bit RISC-V SoC (up to 96 MHz) integrating Bluetooth LE and IEEE 802.15.4 for Thread, Zigbee and Matter designs, with 320 KB SRAM, 128 KB ROM and 19 programmable GPIOs in a QFN-32 package (4 x 4 mm), rated -40 to +105 C on a 3.0 V to 3.6 V supply (ESP32-H2 Series Datasheet v1.1, Table 1-1). The sibling code ESP32-H2FH2S carries 2 MB of in-package flash; neither variant includes in-package PSRAM, and prerelease ordering codes without the trailing S belong to an earlier datasheet revision and must not be mixed with the v1.1 codes. Selection advice: this entry is the bare chip - designs that need an integrated antenna should look at the ESP32-H2 module family instead - and Espressif guidance for single-supply designs is a supply capable of 0.5 A or more.

ESP32-H2FH4S FAQ
What should I check before substituting ESP32-H2FH4S with another Bluetooth LE / 802.15.4 SoC?
Match the full ordering code, not the series name: package (QFN-32), temperature grade and packing all ride on the suffixes. A same-series code in a different package is a different orderable device, so confirm the substitute against the Espressif Systems datasheet before changing the BOM.
